### Remarks

Start metrics collection with [AsyncReadManagerMetrics.StartCollectingMetrics](/engine/6000.6/script-reference/unity/io/lowlevel/unsafe/asyncreadmanagermetrics/startcollectingmetrics.md) and end recording with [AsyncReadManagerMetrics.StopCollectingMetrics](/engine/6000.6/script-reference/unity/io/lowlevel/unsafe/asyncreadmanagermetrics/stopcollectingmetrics.md). You can also enable metrics collection when your program first launches using the command-line argument "-enable-file-read-metrics". You can only collect metrics in development builds.
